Joe Biden says his scandal-plagued son, Hunter, will join him on the campaign trail

Democratic presidential candidate Joe Biden says his son, Hunter — who has been plagued by scandals for years and whose business dealings in Ukraine and China have drawn outrage from Republicans — will be joining the former vice president on the campaign trail.

What are the details?

The Reno Gazette Journal reported Thursday that the elder Biden said "his son will be a visible part of the campaign," telling the paper of Hunter, "He's a fine man. He's been through hell."

Hunter Biden has thus far not been a presence during his father's current race, while scrutiny over Hunter's business dealings during Joe Biden's time as vice president are in the spotlight.

President Donald Trump is now facing an impeachment inquiry after being accused of asking the Ukrainian government to look into the Bidens' interactions in the country. Allegations of impropriety have swirled that Hunter used his position as the vice president's son to gain a paid seat on the board of a Ukrainian natural gas firm.

Hunter's involvement with a Chinese firm have also been called into question, but the Biden camp denies anything nefarious went on and claims the allegations have been refuted.

Anything else?

While President Trump is being accused of withholding aid from Ukraine in exchange for help to expose the Bidens, Joe Biden himself has boasted on tape that threatened to refuse the country $1 billion in aid in 2016 unless Prosecutor General Viktor Shokin was fired.

The Hill's John Solomon reported that Shokin, at the time, "was leading a wide-ranging corruption probe into the natural gas firm Burisma Holdings that employed Biden's younger son, Hunter, as a board member."
